Diabetes occurs when our body is unable to produce enough insulin or does not use insulin effectively. This results in high glucose levels, as insulin is the hormone that helps us turn blood glucose into energy. While diabetes itself is not life-threatening, it can lead to various health complications if not well-managed.

For most of us, our blood glucose levels fall between the healthy range of 4 mmol/l to 7.8 mmol/l. Having a blood glucose level higher than 11mmol/l is a possible indication of diabetes.
